When you declare a static data member (in *.h file), you should also implement it in the *.cpp file:

// MyClass.h file:
//
class MyClass
{
    static int x; 
};
//
// MyClass.cpp file:
//
int MyClass::x; // this line you missed

So you missed to allocate the space for your static variable. Just a declaration of static data members is not enough.

Has x been initialized/defined (in the .cpp file)?

Yes, I declared it in the .h file, and initialzed in the constructor.

Just because it has been declared does not mean it has been defined. Define x in the class' .cpp file. Static members are initialized outside of any class methods (e.g., file scope).

First off, Sorry!, Time is running out for me , so out of panic, I wasn't quite listening to you guys completely. I should have put the definition of the static member again in the .cpp. I did it wrong doing it inside the constructor or a function. Now I put it out side the constructor. It's fine now.

<br />
#include <class.h><br />
int class::x; // ok now!<br />
void class::class()<br />
{<br />
int class::x; //sh*t! sorry.<br />
}<br />
void class::func()<br />
{<br />
<br />
}<br />

Thanks, CL, David, viorel, cederic.. and SORRY FOR THE LATE ACKNOWLEDGEMENT . Need to rush.. thanks a lot.

color in unix/dos??

   Well, VT/XTerm color codes can be used to write in color to a (supported) Unix console. I would suggest using something like the curses library for that, but it has been quite some time since I did any console-coloring so some other libraries may be around.

   If you only need to run the app on Unix but access it from DOS (do you mean a Win32 Console?) and Unix, so that there is only one platform to build for, use curses and connect to it using a terminal emulator that supports ANSI/XCode color codes.

   If you need to build for Unix and Windows, I would suggest that you use the Console Functions in Win32 to do coloring in the Windows/Console build.

   Peace!

Use a masked-edit control. There are several to choose from here at CP. If that is too elaborate for you, derive your own class from CEdit(), and override the OnChar() method. In that method, only allow 0-9 and A-F characters.

Handle the WM_CHAR and allow only 0-9 + A-F + 'x' .

One of the controls I created some time ago supports filtering of input. You can use its implementation as an example of one way to restrict input to a certain set of characters (in your example, "0-9" and "a-f", and optionally "x").

put a flag in the dialog. u should check this flag in the InitDialog. if flag is set, disable the menu.

so before calling the domodal function from the first dialog set this flag.
and when u call DoModal from the second dialog reset the flag..
